Did you know that ...
... the Italian ponies never have a forelock?
... My Little Pony was also procuded by other factories in different countries, which used the same molds, but different colors? These are known as "nirvana's" as they were produced in much smaller amounts and are therefore rare finds nowadays.
... the year underneath one of the hooves refers to the year in which the pony's pose was introduced, and not to the year in which the pony was created/issued? So ponies that appeared in e.g. 1989 can have the year 1983 marked on them.
... Fairy Tail Birds were produced by Hasbro, but have nothing to do with My Little Pony?
